Description
Technical Field
The utility model relates to a railway freight transportation is with executing blockade tapered end field, concretely relates to two steel ball railway execute blockade tapered ends.
Background
In the railway freight transportation, after goods are loaded in boxcars and containers, doors of the boxcars and containers are sealed by electronic sealing locks according to regulations, and the perfect and missing sealing locks are important certificates for complete connection of the number, the quality and the quantity of the goods during and after transportation of trains.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a two steel ball railway sealing lock tapered ends, solve the problem that current railway is easily opened with sealing lock.
In order to solve the technical problem, the utility model adopts the following technical scheme:
the utility model provides a two steel ball railway sealing lock, includes non-through lock and locking lever, open at the top that non-through lock has the lockhole, and the steel ball mounting groove that has two downward sloping settings is opened respectively to the inner wall of lockhole on two different heights, and two steel ball mounting grooves are located the left and right sides of lockhole inner wall respectively, are equipped with spring and steel ball in the steel ball mounting groove, and the lower part of steel ball passes through the spring and links to each other with the end cap that sets up in the bottom of steel ball mounting groove, and the part that is less than steel ball volume half under the natural state emerges from the notch department of steel ball mounting groove, the one end of locking lever links to each other with the top.
Adopts a double-steel-ball structure, a double spring and double steel balls are arranged in the lock hole, when locking, the end of the lock rod, which is provided with a steel ball clamping groove, is inserted into the lock hole of the non-through lock head, so that a steel ball with low height is clamped into the steel ball clamping groove to complete locking, in the locking state, because the free tolerance clearance of the lockhole and the lock rod is very small, the insertion range of the thin steel sheet can only cover one fourth of the width of the clearance, the two steel ball mounting grooves in the application are oppositely arranged, so that the thin steel sheet can only stir one steel ball, therefore, when the locking rod is pulled upwards after the locking steel ball with low height is pulled by the thin steel sheet, the steel ball with higher height positioned at the other side of the locking rod can be clamped into the steel ball clamping groove to play a locking role in the process of pulling up the locking rod, therefore, the double steel balls can effectively play a role in theft prevention, and the anti-theft capacity of the utilization gap is effectively increased, so that the safety of cargo transportation is ensured.
As a further preferred aspect of the present invention, the steel ball is a solid steel ball.
As a further preferred aspect of the present invention, the outside of the non-through lock is coated with a plastic layer.
The plastic layer is arranged, the corrosion resistance is good, and the whole lock head is seamless in a locking state.
As a further preferred embodiment of the present invention, the plastic layer 7 is fixed by bolts disposed in bolt holes on both sides of the lock hole and inserted into the bolt holes.
Compared with the prior art, the utility model discloses can reach one in following beneficial effect at least:
1. simple structure, convenient to use, convenient operation and installation in narrow space have adopted two steel balls and double spring structure, and the steel ball is reasonable with the locking lever cooperation in the tapered end, plays the dual fail-safe effect, has effectively increased and has utilized clearance theftproof ability to guarantee freight safety.
2. The plastic layer can wrap the exposed point at the sealing position of the plug into a whole, and the lock head has no gap as a whole in a locking state.
3. The plastic layer has good corrosion resistance and is more portable.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Specific example 1:
fig. 1, fig. 2, fig. 3 show that two steel ball railway sealing lock tapered ends, including non-through tapered end 1 and locking lever 2, open at the top that non-through tapered end 1 has lockhole 11, the inner wall of lockhole is opened the steel ball mounting groove 3 that has two downward slopping settings respectively on two different heights, two steel ball mounting grooves 3 are located the left and right sides of lockhole 11 inner wall respectively, be equipped with spring 4 and steel ball 5 in the steel ball mounting groove 3, the lower part of steel ball 5 is passed through spring 4 and is linked to each other with the end cap 13 that sets up in the bottom of steel ball mounting groove 3, the part that is less than 5 volume halves of steel ball under the natural state emerges from the notch department of steel ball mounting groove 3, the one end of locking lever 2 links to each other with the top that non-through.
Adopts a double-steel-ball structure, a double spring and double steel balls are arranged in the lock hole, when locking, the end of the lock rod, which is provided with a steel ball clamping groove, is inserted into the lock hole of the non-through lock head, so that a steel ball with low height is clamped into the steel ball clamping groove to complete locking, in the locking state, because the free tolerance clearance of the lockhole and the lock rod is very small, the insertion range of the thin steel sheet can only cover one fourth of the width of the clearance, the two steel ball mounting grooves in the application are oppositely arranged, so that the thin steel sheet can only stir one steel ball, therefore, when the locking rod is pulled upwards after the locking steel ball with low height is pulled by the thin steel sheet, the steel ball with higher height positioned at the other side of the locking rod can be clamped into the steel ball clamping groove to play a locking role in the process of pulling up the locking rod, therefore, the double steel balls can effectively play a role in theft prevention, and the anti-theft capacity of the utilization gap is effectively increased, so that the safety of cargo transportation is ensured.
